Penske declined comment Monday but said an announcement is expected soon. It’s likely the team lands with Chevrolet given Roger Penske’s connections, but at this point, it’s unclear if that manufacturer has two engine leases to give. For sure it has the one initially designated for Ed Carpenter Racing. Chevrolet’s Jim Campbell recently told the Associated Press that the cap would be 15, but two Dragon cars would make 16.

Dragon has a lot of work to do in a short period. The rookie program that Legge is scheduled to participate in is Thursday at Indianapolis Motor Speedway. Bourdais also must pass a refresher session at IMS since he hasn’t raced on an oval track since the 2006 season in Champ Car. He competed in the 2005 Indianapolis 500 with Newman/Haas Racing.

Barring more changes, Lotus will be left with HVM Racing’s car for Simona De Silvestro and the one confirmed Monday for Jean Alesi at Fan Force United, a Firestone Indy Lights team moving up to the IndyCar Series for the 500.

The result of the latter is 33 cars for the 500, which opens for practice Saturday.
